Video - How to Be Correct About Everything All the Time brings up a great example that showcases how compassion is a basic human trend:
Archeological findings show that a member of homo erectus lived around 2 million years ago to the age of 40, while missing most of his teeth during his lifetime. This means that someone had to be taking care of him, and was practicing compassion.
Even though Almost all of us are ignorant about almost everything and that has been like that for a long time, compassion and kindness are the things that have sustained our ancestors through all this time.
As exurbia puts it: "Ignorance is in our bones, but kindness is in our DNA"
